- Thanks for posting the Quadra benchmark results. The FPU really skews
- not only the Math and FPU results, but also the Overall and Bench
- Average.
-
- My guess is that with the FPU, the LC II with 50mhz PowerCache would be 20-
- 30% slower in all the CPU and math-related benchmarks. The disk benchmarks
- seem to be limited in both cases by the disk itself (virtually identical
- readings) so we can't tell how much better the Quadra might be without
- faster disk drives. The graphics performance of the Quadra seems to be
- the big difference, and you can't even put a graphics card in the LC II
- once the accelerator is in there.
-
- I expect that the 33mhz '040 PowerCache due out soon will beat the
- Quadra 700 and 900 on the Math and CPU related stuff, and be very close to
- (possibly even ahead of) the Quadra 950 in these areas. The 16-bit data
- path of the LC II has very little effect once you go to an external
- cache. The Quadras will be somewhat faster in SCSI transfers (if you
- have a fast enough disk to bring out the difference) and will be much
- better in graphics performance (not to mention the ability to drive big
- monitors). Naturally the Quadras have a lot of expansion capabilities
- (including RAM) that the LC II doesn't have. Nevertheless, for tons of
- raw power in a very small box for relatively little money, I can't see how
- the LC II/PowerCache combo can be beat.
-
- Thanks again,
